I know we’ve threatened this before, but there’s going to be a little instability in all of our breathtaking cartoon news over the next week or so while we transition Frederator Blogs over to the tumblr platform. We’ll fill you in on the details (and problems) when the process is done, but for now, forgive us.

Update, May 2011: We’ve completed our changes. For a little more explanation, just click here.

I joined tumblr at the beginning, before then really, since founder David Karp was our high school intern in 2001 and then set up his developer business at Frederator/NY in 2006. And, Adventure Time fans have followed us over there. Obviously, they’ve spread through the world like a wildfire, growing to the 40th largest site on the internet.

Inside of three years our friend David Karp has built tumblr into one of the top 50 sites on the internet (”…it is adding 25,000 new accounts daily, and each month it serves up 1.5 billion page views,” says The New York Times, *and* it’s the coolest place to work, says Time Out New York. “… and it’s run by just a dozen employees.”

Our friends at tumblr have worked incredibly hard and well deserve their next level, a third round of funding from their main venture capital partners.

I’ve been involved with founder DavidKarp since he came to Frederator/NY as a high school intern. He went on to build our first blogging platform and invent Channel Frederator before renting a corner of our office to build tumblr. I joined their board at its inception, and there no way for me to describe how great it feels to work with these folks.
